Future value = p × (1+ i)t `"present value" = "p" / (1 + i)^"t"` what would be the value of $100 after 10 years if you earn 11 percent interest per year? a. $259.37 b. $283.94 c. $110.46

B)  (in $)

Step-by-step explanation:

Value of $100 after 10 years  if I earn 11 %  interest per year is given by,

$

 (in $)

We know that if,

Principal= P

Rate of annual compound interest = r %

Time = n year

then amount, A  =

the correct answer is $7.38

step-by-step explanation:

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
